When an ADR is recovered, is high speed stability regained?
If 2 ADR's are recovered, is low speed stability regained?
Is VLS redisplayed?
There are all valid questions.
We have been told ALT2 was latched, but still the FD bars reappeared so 2 ADRs ceased their disagreement.
It is said that high speed stability is lost in case of ADR DISAGREE but is it back when ADR agree again ?
It is said that low speed stability is lost in case of ADR DISAGREE but is it back when ADR agree again ?
AP is also lost if ADR DISAGREE, could it have been reengaged to also follow the reappearing FD bars ?
Sorry, it’s all too complex for me … and I am fully qualified on the bird.
